Summerall had a unique career in the NFL TV booth, beginning as an analyst in 1962 on CBS where he eventually ascended to the lead analyst position alongside the likes of Ray Scott and Jack Buck. Midway through the 1974 season, he shifted to play-by-play and formed a memorable tandem with Tom Brookshier as they called 108 games together over 6.5 seasons. In 1981, he started a 22-year run with John Madden including a move to Fox in 1994. Altogether, Summerall worked 400 games with Madden as his lead analyst with 171 of these coming at Fox. In 2004, Summerall filled in for 4 weeks on ESPNSunday Night Football as Mike Patrick was recovering from a heart attack.

Summerall was a versatile broadcaster who CBS also used on basketball in both the play-by-play and analyst roles. He worked as an analyst alongside Don Criqui on ABA telecasts in the early 1970s. For the 1973-74 season, CBS installed him as the play-by-play voice on the NBA where he called regular season games with Elgin Baylor and the Finals with Rick Barry (after the network fired Baylor during the playoffs). CBS also used Summerall on play-by-play during the first weekend of the 1985 NCAA Tournament where he called games with Larry Conley.

He was the longtime voice of tennis on CBS calling many US Opens with Tony Trabert. And he was the lead announcer on CBS golf telecasts for many years primarily alongside Ken Venturi. Summerall also called some college football as he worked several Sun Bowl games with Brookshier in the late 1970s and handled play-by-play for four Cotton Bowl games on Fox (his final network TV assignments).
